Frank Albert Fetter led Austrian economic thought in the U.S in the early 20th century. Fetter's wrote a comprehensive work on Austrian economic thought titled, "The Principles of Economics" which restored American interest in the Austrian school. Also, a few important economist were trained at the University of Vienna during the 1920's. Eventually, these economists participated in private seminars held by Ludwig Von Mises. Among these economists were Gottfried Haberler, Friedrich Hayek, Fritz Machlup, Karl Menger (son of Carl Menger), Oskar Morgenstern,Paul Rosenstein-Rodan and Abraham Wald, among others. Most recognized the profound techniques the Austrian School developed for micro-economic analysis. However, many of the Austrian school's theories on macro-economics were rejected due to lack of empiricalism and mathematical models. This problem led to many economists rejecting Austrian economic thought in favor of the mathematical models developed by John Maynard Keynes among others. By the mid 20th century there was no distinct Austrian school in the U.S. Also, during this time, the Austrian school began to split due to a disagreement about whether or not neo-classical economic models could be used effectively. Mises fiercely criticized the neo-classical models and was a staunch libertarian believing that any government intervention would only harm the economy. However, Friedrich Hayek found many of the neo-classical models usefull and was not entirely opposed to government intervention. In 1974 Hayek won the Nobel prize for economics alongside Swedish economist Gunnar Myrdal. Thus, public interest in the Austrian school increased and Hayek's research was instrumental in the reemergence of laissez-fair thought in the 1900's.
Many of the ideas developed by first wave Austrian economists have become widely accepted in modern economics. Those theories include Carl Menger's theories on marginal utility, Friedrich von Wieser's theories on opportunity cost, and Eugen Böhm von Bawerk's theories on time preference. Also, Menger and Böhm-Bawerk's criticisms of Marxian economics made noteworthy contributions to modern economics. In 1981, Frich Machlup compiled the usually ideas of economists that are part of the Austrian school.
"Methodological individualism: in the explanation of economic phenomena, we have to go back to the actions (or inaction) of individuals; groups or "collectives" cannot act except through the actions of individual members. Groups don't think; people think.
Methodological subjectivism: in the explanation of economic phenomena, we have to go back to judgments and choices made by individuals on the basis of whatever knowledge they have or believe to have and whatever expectations they entertain regarding external developments and especially the perceived consequences of their own intended actions.
Tastes and preferences: subjective valuations of goods and services determine the demand for them so that their prices are influenced by (actual and potential) consumers.
Opportunity costs: the costs with which producers and other economic actors calculate reflect the alternative opportunities that must be foregone; as productive services are employed for one purpose, all alternative uses have to be sacrificed.
Marginalism: in all economic designs, the values, costs, revenues, productivity and so on are determined by the significance of the last unit added to or subtracted from the total.
Time structure of production and consumption: decisions to save reflect "time preferences" regarding consumption in the immediate, distant, or indefinite future and investments are made in view of larger outputs expected to be obtained if more time-taking production processes are undertaken.
He included two additional tenets held by the Mises branch of Austrian economics:
Consumer sovereignty: the influence consumers have on the effective demand for goods and services and through the prices which result in free competitive markets, on the production plans of producers and investors, is not merely a hard fact but also an important objective, attainable only by complete avoidance of governmental interference with the markets and of restrictions on the freedom of sellers and buyers to follow their own judgment regarding quantities, qualities and prices of products and services.
Political individualism: only when individuals are given full economic freedom will it be possible to secure political and moral freedom. Restrictions on economic freedom lead, sooner or later, to an extension of the coercive activities of the state into the political domain, undermining and eventually destroying the essential individual liberties which the capitalistic societies were able to attain in the 19th century.", "Austrian School"
In the late 18th century and early 19th century Austrian economist Eugen Böhm von Bawerk developed the Austrian theory of capital and interest. This theory states that interest rates and profits are determined by two factors, namely supply and demand in the market for final goods and time preference. Also, the theory links capital intensity with the degree of roundaboutness of production processes. Böhm-Bawerk stated that he law of marginal utility necessarily implies the classical law of costs. Therefore, Some Austrian economists disagree with the idea that interest rates are affected by liquidity preference. According to Mises, inflation was caused by an increase in the money supply. The economic calculation problem is a criticism of socialism that began when Max Weber pointed it out in 1920. Also, that some year Mises published an essay titled, "Economic Calculation in the Socialist Commonwealth" in which he argued that the pricing mechanism in socialist systems wouldn't work simply because the government built all of the equipment necessary for production. Therefore, all of the capital goods put into factories were internal transfers and not purchases. Thus, government officials would be unable to price goods and services accurately and resources would be allocated inefficiently. Later on Mises had conversations about Weber's ideas with his student Friedrich Hayek. Hayek incorporated Weber's ideas into his work including a book titled, "The Road To Serfdom". The Austrian school emphasizes the organizing power of markets. Hayek argued that market prices reflect information, the whole of which is not one to any one individual, which determines the allocation of resources in an economy. According to the economic calculation problem, since socialist systems lack the individual incentives and pricing mechanisms found in capitalist systems, socialist economic planners lack the incentive or the information necessary to make good decisions. The debate of the economic calculation problem rose into the mainstream in the 1920s and 1930s. Eventually, this particular period of debate became known as the socialist calculation debate.
Mises developed the Austrian business cycle theory and Hayet later expanded upon the theory. This theory states that booms are caused by excessive lending that results from low interest rates and low reverves held by banks. Eventually, once the banks run out of money to lend there is a recession because the debt fueled economic cannot continue while businesses and consumers are burdened with debt. This leads to bankruptcies, foreclosers, and mass unemployment. Much of the Austrian school believes that a recession is necessary to rebalance the economy after a long period of malinvestment caused by excessive lending. In other words, the Austrian school teaches that duing a boom excessive lending causes inefficient investments or malinvestment and an inefficient allocation of resources. Therefore, only a recession can cause resources to be reallocated efficiently as debt is slowly either paid off or defaulted on. Ludwig von Mises argued that central banks allow commercial banks to lend money at artificially low interest rates and creates a period of inefficent debt fueled growth. Friedrich Hayek however argued against perfect competition in the banking industry and that central banks were absolutely necessary to ensure the stability of the financial system. It is import to note that some economist within the Austrian school argue for a gold standard because fiat currency, which is back by the government issuing the currency, is not based on the free market. Although, some Austrian economists disagree with this assessment. The Austrian school tends to be libertarian believing that the government should not intervene in the economy. While some modern economists within the school are more accepting of government intervention.
Some economist still argue that modern Austrian economic thought ignores mathematical models in favor of analyzing individual behavior. Also, economists disagree over whether socialism works. Some have pointed to the low rates of poverty and relatively low income inequality in socialist countries such as Sweden. While others have argued that these socialist government are using resources less efficiently then the private and therefore is slowing down economic growth. It is important to note that these socialist countries have components of both capitalism and socialism. In these countries people are free to choose their career, start a business, and make decisions for themselves as a consumer. While the government engages in massive social welfare programs such as universal health care and retains control over certain industry leaving all the other industries to the free market. It is important to note that the Austrian business cycle theory has some truth to it because as we saw in both the 2008 recession and the crash of 1929 debt was heavily involved in both cases. Investors over burdened themselves with debt to buy stock throughout the Roaring 20's and prime mortgage lending fueled the housing bubble. However, the theory lacks components such as explanations for involuntary unemployment and why investors become euphoric during asset bubbles. The problems with a gold standard emerged during the Great Depression when the Federal Reserve could not print more money because there was not enough gold available to back the currency. Eventually, this led to the U.S, along with most countries around the world, moving to a fiat currency that is only back by the guarantee of the federal government. The Austrian school's explanation for inflation fails to take into account supply and demand for goods and services while it argues that inflation is caused by an increase in the money supply. As we saw with oil prices in the 1970's and 1980's inflation was caused by high oil prices due to an embargo on several Middle Eastern countries. Austrian economic thought is useful for micro-economic analysis and rarely useful for macro-economic analysis. Although, there are problems with solely relying on mathematical models for economic analysis.
